I installed BOINC from the ubuntu repos.

When i want to start form the menu i get an error window:

"Impossible d'exécuter boinc manager
le changement de répertoire /var/lib/boinc-client a échoué (permission non accodrée)"

That suggest a permissions problem.

Ok, i managed to changes the permission of the folder. Now i get a boinc manager window that tells me:

"Boinc manager (pre release) ne peut pas démarrer un client BOINC. Merci d'exécuter le client et de réessayer."

Ok, i searched the net and found a workaround: i type in a terminal:

sudo systemctl start boinc-client

Before relaunching the boinc manager. And it finally works; With the GPU enabled. I leave this here in case someone would be in trouble like i was. But what a shoddy work by canonical !

This has nothing to do with Canonical. Systemd is an init process which has replaced all the previous Linux init processes, because it is much cleaner and solves many problems most, if not all, of those previous methods had. It has been the standard init process on all major Linux distributions since 2015.
Systemd is the first process started when you boot, the last to stop when you shut down; it is responsible for starting all the user space processes needed to run a clean system. As far as boinc is concerned, you are right; installing boinc from a repo creates a user "boinc" and a group, also called boinc. The boinc-client script tells systemd to run the client as user boinc.
If you want boinc to start whenever you boot your system, you also need to run the following:
sudo systemctl enable boinc-client

If you want to use the boincmanager gui, you will also need to add yourself to group "boinc":
usermod -a -G boinc <your_user_name>

Thank you for the additional commands. BOINC starts at startup now !

(On the precedent ubuntu versions you did not need to type commands, it started out of the box) Hence the poorer work from Canonical.

I have the same problem on Ubuntu 22.04 and Boinc 7.18.1 + dfsg-4, I get the following information Failed to start "Boinc Manager" failed to go to directory /var/lib/boincclient Permission denied. I followed both instructions and it didn't work.

7.18 doesn't work on Linux. For what is worth the BOINC in the repos of my Xubuntu 22.04 is called 7.20 "preview version".

pre-release to be exact.

I am also having a problem of not being able to attach projects that I already have an existing accounts for., but I can create new accounts and attach the project.The operating system is linuxmint-21.1-cinnamon-64bit. The boinc version is BOINC client version 7.22.1 for x86_64-pc-linux-gnu.
